1 Feeding management of broiler chickens
The broiler chicks were reared and managed at the brooding stage, and 42 days later they entered the broiler rearing and management. Fertility level can be used for ground level raising, net raising or cage raising. The daily management work is: after turning on the lights or dawn every day, when the first feeding, it is necessary to observe the feces and feed intake of the chickens, and turn off the light chickens at night. After quiet, go to the coop to hear if there is abnormal breathing. Feeding and feeding water, catching chickens should be light, can not be rough, keep chickens clean, hygienic and quiet, and make necessary records every day. The main points for rearing and management of broiler chickens are as follows: (1) When the brooding period is shifted to the rearing period, when the brooding material is replaced with the bred material, it should be gradually replaced in proportion. The breeding room temperature should be similar to the temperature of the brooding house, and the flock should be adapted and then gradually reduce. 2 Control the time and intensity of light to prevent the emergence of flea. 3 Strengthen management before and after prophylactic injection and administration, and reduce the stress response of the flock. 4 Feed the qualified broilers so that the birds have a standard weight and moderate feed intake.
2 Feeding Management during Production Period
2.1 Preparation before transfer: Broilers should be transferred to the laying house at about 18 weeks of age. All preparations for the house should be completed before the group is transferred, including house cleaning, disinfection, required troughs, and sinks. , lighting fixtures, etc., when the first time the group of chickens to drink water, vitamin C can be added to the water in order to improve the low resistance of chicken handling stress.
2.2 Management of the lighting system: After 20 weeks of age, laying hens will be given 1 hour of light each week for the first 3 weeks of age, and will be increased by half an hour each week, reaching 16 hours or 16.5 hours, and will remain stable when artificially supplemented with light. , Turn on and off the light every day and keep the light time as stable as possible. While increasing the light, the quality and quantity of the feed must be increased simultaneously, so that the hen can get enough nutrition to reach the peak of egg production.
2.3 Daily management: When the keeper enters the coop every day, he must observe the feeding, drinking, excrement, and mental status of the flock, pick out the sick, disabled, and weak chickens in time, detect dead chickens, and find out that the flock is in poor spirit and analyze immediately. Find the cause and take the appropriate action. Keep chicken coops, troughs and feed troughs clean and tidy, and carefully record the daily number of eggs, the number of chickens that died, the number of broken eggs, the number of soft eggs, the feed intake of chickens, and the temperature of the chicken house.
2.4 After 18 weeks of age (before opening), the weight of the chicken was measured and compared with the standard weight of the same age of the breed, and the feed nutrition standard was adjusted accordingly so that the chicken population could reach the standard. 25-40 weeks of age is the peak period of egg production. Every week, the body weight should be measured once to check whether the feed has reached the production requirements.
2.5 About 80% of laying hen's feeding costs are feed expenses. Using high-quality, full-price ingredients to reduce feed loss is the key to improving hens' feeding efficiency.
2.6 Artificial Compulsory Moulting: When the supply of spare hens is not normal, the cost of production of chicks, feed, labor, etc. is too high, or the price of culled hens is low, mandatory artificial moulting can be implemented to prolong the laying hen's egg production life. . The so-called artificial forced moulting is artificially stimulating the laying hens for nearly one year, such as stopping the water, stopping the material, and stopping the light, so that the hens can quickly stop production and moulting to improve the egg production and egg quality.
